Radium is the most reactive in this group.
The most chemically reactive metals are the alkali metals. Francium is the most reactive of these and of all metal (although it is present on earth only in exceedingly small quantities, due to its radioactivity).The most reactive element available in useful quantities in Flourine.
Alkali metals are the most reactive group of metals due to their low ionization energy, which allows them to readily lose their outermost electron to form cations. This reactivity increases down the group, with francium being the most reactive alkali metal.
The most reactive elements are usually found on the left side of the periodic table in Group 1 (alkali metals) and Group 17 (halogens). Alkali metals like sodium and potassium are highly reactive due to their tendency to lose electrons, while halogens like fluorine and chlorine are reactive due to their tendency to gain electrons.
The most reactive group of metals in the periodic table is Group 1, the alkali metals. These metals are highly reactive due to their low ionization energies, which means they readily lose their outermost electron to form positive ions. This reactivity increases as you move down the group due to the decreasing ionization energies.
alkali metals
because it has the most number of electrons in the alkali metal group
Francium is the most reactive alkali earth metal. It is highly reactive due to its low ionization energy and large atomic size, making it eager to react with other elements. However, francium is extremely rare and radioactive, so its reactivity is mostly studied through theoretical predictions.
Francium.
It is located, in the periodic table, with the metalloids. However, it is a transition metal.
Yes, alkali metals are more reactive than alkaline-earth metals. All atoms want to have 8 electrons in their outer shells. Alkali metals have to give one electron away, where as alkaline-earth metals need to give two away which is less energetically favorable.
I think alkali is the most reactive one.
Hydrogen.
Radium is the most reactive in this group.
Group 1, the Alkali Metals, which are extremely reactive.
Reactivity increase down the group.Ceasium is the most reactive.
